Elliptical silicon carbide graphite crucible and preparation process
The invention provides a preparation process of an elliptical silicon carbide graphite crucible, and relates to the field of smelting crucibles. The preparation process of the elliptical silicon carbide graphite crucible comprises the steps of S1, adding 35%-45% by mass of graphite, 38%-48% by mass of silicon carbide and 7%-27% by mass of an additive into a mixing mill; S2, filling a mold with the mixed material in the S1, sealing the mold, and putting the sealed mold into a cold isostatic press to be pressed; S3, taking out the pressed mold, disassembling, and removing redundant burrs on the edge of an upper opening of the product blank; S4, putting the product blank into a curing kiln to be dried; S5, coating the dried product blank with an anti-oxidation coating; and S6, enabling the product blank to be subjected to calcination forming machining. The prepared crucible has the advantage of good heat-conducting property. The elliptical silicon carbide graphite crucible comprises the crucible prepared on the basis of the preparation process, and an adjusting plate is arranged in the crucible. The crucible solves the problem that molten metal in the crucible is not easy to scoop.
本发明提出了一种椭圆形碳化硅石墨坩埚的制备工艺，涉及熔炼坩埚领域。一种椭圆形碳化硅石墨坩埚的制备工艺包括以下步骤：S1，在混炼机内加入质量比为35％‑45％的石墨、38％‑48％的的碳化硅、7％‑27％的添加剂；S2，将S1中的混合物料填充在模具内，对模具进行密封，密封后的模具放入冷等静压机内进行打压；S3，将打压后的模具取出拆卸，并去除产品毛坯上口边缘处多余的毛刺；S4，将产品毛坯放入固化窑内进行干燥；S5，将干燥好的产品毛坯涂上抗氧化涂层；S6，产品毛坯进行煅烧成型加工。制成的坩埚具有导热性能好的优点。一种椭圆形碳化硅石墨坩埚，包括基于上述制备工艺制备的坩埚，上述坩埚内设置有调节板。该坩埚解决了坩埚内的金属液不易舀取的问题。
